Embodiment Construction

[0031] Reference will now be made in detail to exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[0032] A healthy knee joint includes the interface between the distal end of the femur and the proximal end of the tibia. If a healthy knee is damaged, eg, by injury or disease, knee surgery may be required to restore the joint's normal structure and function. If the damage to the knee joint is severe, a total knee arthroplasty ("TKA") may be required. TKA typically involves removal and replacement of the damaged portion of the joint with one or more prosthetic components.

[0033]During some TKA procedures, one or more of the cruciate ligaments (including the anterior and / or posterior cruciate ligaments) may be left intact to be re-used with the prosthetic implant to form the new knee joint. In these "crucis-sparing" applications, the prosthetic implant component can be configured to avoid interference with or impi...

Abstract

A method for generating a customized haptic boundary based on a patient-specific anatomy includes identifying a standard haptic boundary based on a geometry of a virtual implant model to be implanted on the anatomy. The method also includes identifying a reference feature associated with a virtual implant model and determining an intersection between the identified reference feature and a virtual model associated with an anatomy of the patient. An anatomic perimeter at the intersection between the identified reference feature and the virtual model of the anatomy is identified and an one anatomic feature is determined on the virtual model of the anatomy. The standard haptic boundary is modified based on the anatomic feature to generate a customized haptic boundary.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to US Provisional Patent Application No. 61 / 922,740, filed December 31, 2013, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates generally to force feedback systems associated with computer-assisted surgery ("CAS") systems, and more particularly to systems and methods for customizing interactive haptic boundaries associated with CAS systems based on patient-specific information. [0004] The knee joint includes the interface between the distal end of the femur and the proximal end of the tibia. In a normally functioning knee joint, the medial and lateral condyles of the femur pivot smoothly along a meniscus that attaches to each of the medial and lateral condyles of the tibia. When the knee joint is damaged, the natural bone and cartilage that form the joint may not be able to articu...
